538 SUMMARY OF (JUERENT RESEARCHES RELATING TO 



and MarsupeUa badensis in Croatia ; (69) Oephalozia Loitlesbergeri, a new 

 species, with description of its microscopic characters ; (70) Pleurozia 

 purpurea, description and iigures of the female inflorescence, hitherto 

 unknown in a perfect state ; (71) Riccia Pearsoni Steph. is autoicous, 

 and agrees with R. nigrella in all points, and cannot be separated from 

 that species. 



In a further instalment* he treats of (72) the occurrence of Ceplmlozia 

 macrostachya in Middle Europe ; (J'a) a new station for G. Loitlesbergeri. 



Bryum languardicum.t — P. Jansen describes the microscopical struc- 

 ture of Bryum languardicum, a new moss of the sub-genus Gladodium, 

 related to B. archangelicum, and gathered on Piz Languard near Pontresina 

 at an altitude of about 11,000 feet. 



Pylaisiadelpha.f — J. Cardot gives a description of the structure of 

 Fglaisiadelpha, a new genus of Entodontacea3, containing two species, 

 one from Mexico, the other from India. The genus has the peristome 

 of Pylaisia, but differs in having its operculum longly rostrate, and the 

 alar cells of its leaves inflated like those of PJiapliidostegiurn. 



New Scottish Mosses.§ — J. Stirton describes the microscopic charac 

 ters of four new mosses collected near Gairloch in Koss-shire — Grimmia 

 rubesceiis, G. undidata, Bryum elegantulum, Barbula incavata. In the 

 same district on debris of Torridon rock was found Lemobryum pumilum 

 (Michx.), a species with cucullate leaves. A close search for it was advo- 

 cated by W. P. Schimper during his visit to England in 1865. At 

 Onich, on Loch Linnhe, a fruiting tuft of Plagiothecium Muelleri was 

 gathered near sea-level ; never before has it been found in fruit in 

 Britain. 



Italian Ricciaceae. || — C. Massalongo publishes an illustrated account 

 of the RicciacefB of the Italian flora, and to make his monograph the 

 more complete he gives descriptions also of the other species found out- 

 side Italy, but within the Mediterranean basin or in Europe. He 

 describes and figures the structure of TesseVma (1 species), Ricciocarpus 

 (1), Riccia (23). He also enumerates the twelve general characters of 

 Riccia, and arranges them according to their relative importance, assigning 

 the lowest place to the monoicous or dioicous inflorescence. A key to 

 the species and an index are provided. 



North American Sphagnum.lT — A. Le Eoy Andrews publishes fur- 

 ther notes on North American Sphagnum — namely, on two species of 

 the sub-genus Inophloea — S. papillosum and S. erythrocalyx. He adds 

 critical remarks upon the minute characters employed for the discrimina- 

 tion of the species, and shows that 8. Waghornei is identical with S.
